First of all it is not from the 1960s, probably more like the early 1970s, before 1970 the Jap makes used to mark the dial frequencies in KC and MC not KHz and MHz, if you open it up you may find some date codes that will narrow it down. As for the other issue with the volume blast when you turn it of chances are it needs the electrolytics changed and maybe a few resistors by now.
